If Hector Olivera needs Tommy John surgery, there will be an extra year and $1 million added to Olivera’s contract, according to an industry source. It is currently unclear whether or not he’ll need Tommy John surgery, but one source says “he does have something” wrong within his elbow.

John Lackey had a similar clause in his five-year, $82.5 million deal with the Red Sox and will make just $507,500 from the Cardinals this year because of it. He needed Tommy John surgery in October 2011.

Olivera was primarily a second baseman in Cuba, but the Dodgers will likely try him at third base.

He was a .323/.407/.505 hitter in 10 seasons with Asvispas de Santiago of Cuba’s Serie Nacional.
